No it won't but on a beach catamaran you never save 20 kg in one go.

It is however an example of what Matt McDonald said in his interview. New materials and techniques will become available (come online) over time allowing a drift downwards in ready to sail weights.

I will keep an eye on your blog to see how the rigging holds up over the long term. I got dyneema trap lines since 1998 now and they are brilliant, no issues at all. If the standing rigging behaves similar (including chaff-resistance) then it will be an attractive option.
